panying drawings forming part thereof, in

which:

Figure 1, is a sectional view of the strainer structure in the positionof use; Fig. 2, is a similar sectional view illustrating certain of theparts in separated condition, and Fig. 3, is an enlarged sectional viewof a portion of the structure. v In the drawings, 1 represents thestrainer structure which may be, generally speaking, in the form ofafunnel, adapted to fit. into a suitable receptacle and through whichmilk to be contained in such receptacle may be passed. The strainerstructure has an upper annular portion 1*; a gradually contractingmiddle portion 1", and a contracted.

lower portion "1. Over the upper portion a section of cheese-cloth orsimilar material indicated at 2 is preferably stretched, and

through this the milk is initially passed. T 0 keep this cloth in asubstantially taut condition, a wire or band 3 may be stretched aroundthe same in engagement with the portion 1* of the strainer structure, inthe manner indicated. Vithinthe lower contracted portion 1 of thestructure, we pro-.

vide straining means consisting of a sleevelike element 5, substantiallyfilling or fitting within such contracted portion, such the lowerelement 5 having a flange 6, or a series of.

projections to overlie the inclined wall of part of the middle portion 1of the funnel, and over the topof said sleevelike member a section offine wire gauze, indicated at 7, is secured. The bottom of thecontracted portion 1 is covered by a wire screen 8, preferably coarse,and between the same and the sleeve-like element f straining means areprovided in the shape Specification of Letters Patent.

preferably confined between two layers of cheese cloth or similarmaterial, indicated at 15 and 16. Fig. 2 shows the manner in which thisportion of the structure is assembled. The two sections of cheese-clothwith the layer of absorbent cotton between the same are placed in thelower part of the tapering portion 1 of the structure; then the tubularsleeve-like element 5 is placed over the same, and then forced into thelower contracted part; compressing the absorbent cotton at or adjacentthe margin of the same, and pressing the bulk of the same against thecoarse wire bottom screen 8 the flange 6, (or projections) contactingwith the inclined walls of the central portion of the structure. Thesection of cheesecloth at the top of the structure is then stretchedinto place and confined, and then the device is ready for use.

It will be seen that all of the milk passed into the straining structuremust pass through the absorbent cotton. In practice, the flange 6 mayhave a tight fit adjacent the inclined walls so that practically no milkpasses down between the same.- Should milk pass such structure, however,it will be trapped slnce the absorbent cotton is compressed to such anextent as to prevent its ready passage, and if it should pass, it mustgo through'such absorbent cotton.

. \Ve claim: v

1. In a strainer, the combination of a re upper and lower surfaces,saidsleeve-like element having a foraminous top and being open at thebottom and having an external diameter about equal to the interiordiameter of said outlet, the edges of the fabric covered surfaces of thebody of fibrous ma: terial extendingbeyond the body and adapted to beturned up against the edge thereof and against each other and to beconfined between the wall of the tubular outlet and the wall of saidsleeve-like element.

2. The combination, in a milk strainer, of a substantially funnel-shapedshell or casin having a contracted outlet, a supplementa sleeve-likeelement disposed therein, a coarse wire bottom for said funuel-shapedst-ructure, a fine gauze wire top for the outlet of said sleeve-likeelement, a layer of absorbent cotton interposed between the sleevenamesto this specification, in the presence like element and the coarse wireat the botof two subscribln g witnesses.
